其前身上海益昌薄板有限公司成立于1989年，1998年上海宝钢集团公司增资控股益昌薄板，更名为上海宝钢益昌薄板有限公司。

2004年4月1日，宝钢股份全资收购宝钢益昌，益昌整体进入宝钢股份产销序列，成为宝钢股份的冷轧生产单元之一——冷轧薄板厂，定位于专业生产薄规格精密冷轧板卷和镀锡板卷。

2000年以来，冷轧薄板厂的主轧机进行了大规模的设备改造，同时新建了高电流密度电解清洗机组、连续退火机组、镀锡镀铬机组、重卷机组以及国内第一条二次冷轧机组，并对罩式退火机组能力进行了扩容，使冷轧薄板厂的主题生产设备达到了世界先进水平，设计成品规模为100万吨/年。

其产品包括普冷薄板45万吨/年，电镀锡板35万吨/年，电镀铬板20万吨/年。

Cold Rolled Steel SheetC old Rolled Steel Sheet Mill of Baosteel is a production unit specialized in producing thin gauge cold rolled steel sheet as well as tin plate. Previously it was named as Shanghai Yichang Steel Strip Company Ltd. which was founded in 1989. In 1998 Shanghai Baosteel held a majority of share of Yichang through increasing investment and then changed its' name into Shanghai Baosteel Yichang Steel Strip Company Ltd. On Apr.1, 2004 Baosteel wholly owned Shanghai Baosteel Yichang Steel Strip Company via buying all the other registered capital of it. From that time whole Yichang hasentered the production and sales systemof Baosteel and become one of thecold rolled production unit of Baosteel,Cold Rolled Steel Sheet Mill, which isspecialized in producing thin gaugeprecise cold rolled steel sheet as well astin plate.From 2000, the old cold rolling mill hadbeen revamped drastically. Meanwhilenew electrolyze degreasing line with highcurrent density, continuous annealingline, new tinplate line, TFS line, recoilerand double reduce cold rolling millwhich is the first production line in Chinawere built up and also some new batchannealing furnaces were founded andput into production. In that case, thegeneral production equipments of ColdRolled Steel Sheet Mill are now of worldadvanced level and the design annualproduction capacity is one million.The products manufactured by thismill include cold rolled steel sheet incoil(450,000t/a), tinplate(350,000t/a), andtin free steel(200,000t/a), etc.Cold Rolled Steel Sheet冷轧薄板产品生产流程Production flow of ColdRolled Steel Sheet Cold Rolled Steel SheetCold Rolled Steel Sheet酸洗机组1990年从奥地利鲁士纳公司引进的浅槽式“推拉酸洗机组”，最大运行速度为每分钟180M，年酸洗能力为55.8万吨，并配有酸再生装置，酸回收率99%以上。

冷轧机组2000年引进日本三菱技术进行了全面技术改造，改造后的轧机由五机架四辊轧机组成，具有6台激光测速仪，五台X射线测厚仪。

轧制能力提高到90万吨/年，轧制速度提高到1800M/min。

脱脂机组2002年引进国内第一条大型高速自动化电解清洗机组，由日本川崎制铁提供技术，美国ROCKWELL公司负责电气设计制造，机组最高速度900米/分，是目前世界上最先进的电解清洗机组，设计年产量55万吨。

Cold Rolled Steel SheetCold Rolled Steel SheetPickling lineT he push and pull pickling line with shallow tank was imported from Austrian Ruthner company in 1990. Its' max. runningspeed is 180m/min and the annual capacity is 558,000mt. It is equipped with acid regeneration system and the acid recycleratio exceeds 99%.Cold Rolling MillT he rolling mill was general revamped in 2000 by means of importing the technology of Mitsubishi Heavily Industry and Mitsubishi Electric. Now the continuous rolling mill is composed of 5 stands with four high, equipped with 6 sets of laser speed detector and 5 sets of x-rays thickness gauge. The annual rolling capacity is 900,000mt. The max. rolling speed can reach 1800m/min.Degreasing lineI t was built in 2002 and is the first big automatic electrolyte cleaning line with high speed in China. The technology of this line is supplied by Japanese Kawasaki Steel Corporation. America ROCKWELL company is responsible for the electric design and manufacture. The max. speed of the line is 900m/min. It is the global most advanced electrolyte cleaning line. The design annual production capacity is 550,000mt.退火机组现有46台强对流全氢罩式退火炉，其中奥地利EBNER公司罩式炉台38个，德国LOI公司罩式炉台8个，设计年产量46万吨。

全氢罩式退火炉采用强制对流的光亮退火工艺，使用的氢气纯度高达99.999%。

平整机组1990年从美国TIPPINS公司引进的双机架平整机组，机组最高速度1500米/分，年生产能力为50万吨。

目前该机组正进行整体改造。

二次冷轧机组2004年从日本三菱－日立公司引进，是国内第一条二次冷轧兼平整机组，采用双机架六辊UCM轧机，平整模式最大轧制速度1500米/分，二次冷轧模式最大轧制速度1200米/分，设计年产量25万吨。

二次冷轧产品的最薄厚度达到0.08mm。

横切机组1990年从美国DALTA公司引进，最大线速度为150米/ 分，设计年产量10万吨。

Cold Rolled Steel SheetCold Rolled Steel SheetAnnealing FurnaceT here are 46 sets of full hydrogen forced convection batch annealing furnace( including 38 sets from Austria EBNER and 8 sets from Germany LOI).
